SPECIFICATION forming part of Letters Patent No. 781,779, dated February'7, 1905.

Application filed May 12,1904. Serial N 207,532-

Be it known that I, NATHANIEL Lonmm). a citizen of the United States ofAmerlca, and 1 a resident of \Vorcester, in the county of \Vorcester andState of Massachusetts, have invented certain new and usefulImprovements inliovernors, of which the following is aspecitic-ation. p

This invention relates to mechanism for controlling the speed of variousmotors, and more particularly to such governors which serve to applypower from an auxiliary source to effect the movements of the valve,gate, or other regulating device.

It consists in certain novel features of construction and arrangement ofparts, which will be readily understood by reference to the descriptionof the drawings and to the claims to be hereinafter given.

Of the drawings. Figure 1 represents a plan view of a governor embodyingthe features of this invention. Fig. 2 represents a rear elevation ofthe same, a portion of the driving mechanism being shown removedtherefrom. Fig. 3 represents a left-hand end elevation of the same. Fig.& represents a longitudinal central vertical section looking toward thefront of the machine. Fig. 5 represents a sectional elevation of thesame, the cutting plane being on line 5 on Fig. i. Fig. 6 represents anend elevation of the drivingpul- Icy and the controlling mechanismcontained therein. Fig. T represents a detail of the spring tensiondevice for controlling the centrifugal weights. Fig. 8 represents a faceview of one of the clutchmechanisms. Figs. 2) and I!) representsectional details showing the key for securing the actuating-shaft toits clutch member and its connection with the operating member. Fig. 11represents a section of the operating member, showing the relativepositions of the recesses for the toggle members of the two pairs 'ofclutches. Fig. 12 represents a sectional elevation of the devices forconnecting the primary driver and the operating-member lever. Fig. 13represents a sectional elevation of the revoluble Fig. H repsleeve andindicator mechanism.

resents a sectional detail of the primary driving-shaft and its slidablecotiperating mem- 5 her. Fig. 15 represents a sectional detail of theoperating member actuating-collars, and Fig. 16 represents a sectionaldetail of the controlling-rod rack and its cooperating gear. Figs. 6. 8,It), and II are drawn to a larger scale, and Figs. 7, 2), 12 to .16,inclusive, are drawn to a still larger scale.

Similar characters designate like parts throughout the several liguresof the drawings.

The numeral l0 designates a suitable baseplate, on which is journalcd instandards II a shaft 12 for connection with the gate or regulatingdevice for controlling the speed of a motor as. for example, aturbine-wheel which shaft may be appropriately termed amotor-controlling" shaft. In the standards l1 may be also journaled apreferably hollow actuating-shaft 13 for the motor-controlling shaft,they being conveniently connected by 7 spur-gears l5 and 16, the latterhaving secured thereto a disk ll, which is preferably relcasably lixedto the shaft 12 by some such connector as a pin-clutch 17, carried by anarm 18, fast upon the shaft and engaging an opening in the disk It.

The actuating-shaft 13 has keyed to it the inner members of clutches orconnectors 24) 21, the outer members of which are lixed to or formedintegrally with driving-shafts respectively, which are here shown ashollow, surrounding the actuating-shaft and iournaled in the standards21L, supported from the baseplate between the standards 11.

The driving-shafts may be conveniently ro- 5 tated in oppositedirections by bevel-gears 25, meshing with a bevel-gear 2b, lixed toashaft 2T, conveniently journaled in a bracket on the standard 2i androtated at the desired speed from any suitable source of power through apulley 28. The outer member of each clutch may consist of a llanged disk2%), while the inner coactingmember is preferably formed of a disk 30,provided with an annular frictional surfacelfli. adapted to coact withthe inner face of the outer clutch member 22). The

actuating-shaft 13 has also keyed thereto laterally-projecting arms 31,to the outer end of which are articulated at 33 connecting arms orsupports 34, to the opposite end of which are pivoted at 35 the shoes36, the bearing-surface of which coacts with the inner periphery of theflanged disk 29.

The shoes 36 are provided with a boss 37, the outer end of which isprovided with a recess or socket to receive the ball end 37* of theadjustable toggle member 38, the opposite end of which is provided witha ball end 38 which enters a recess or socket formed in the operatingrod or member 39. In the normal positions the adjustable toggle member38 is slightly out of radial line with the axis of the operating-rod 39,with the shoes 36 slightly removed from contact with the inner peripheryof the flanged member 29. When, however, the clutch members 29 and 30are cooperating to rotate the actuating-shaft 13, with its radial arms31, in the direction of the arrow (0 on Fig. 8, the arms 34 will movethe shoes 36 in the direction indicated by the arrow 6 on Fig. 8, whichmovement will cause the toggle member 38 to be moved into a positionradial to the axis of said operating member 39, thereby causing thelatter to be revolved aboutits axis in unison with the driving clutchmembers 29 and 30.

Intermediate the gears 25 a grooved collar '40 is mounted upon theactuating-shaft 13, and

a pin 41 extendsdiametrically from side to side of said collar, said pinextending through a slot 42 in the actuating-shaft and through theoperating-rod 39, so that endwise movement of the collar willtransmitits movement to the operating-rod 39 without effecting any longitudinalmovement of the actuating-shaft 13.

The groove of the collar 40 has mounted therein the annular ring 43,said ring being mounted in the bifurcated lever 44, pivoted at 45 and bywhich an endwise movement is imparted to said collar for the purpose ofmoving the operating-rod 39. Either end of said rod 39 is provided withan adjustable member 46, the inner end of which bears upon a key 47,secured to the hub of the inner clutch member 30 and extending throughslots 48 in the actuating-shaft 13 and through slots in theoperating-rod 39. It is obvious by an inspection of the drawings that inthe normal position the inner clutch members 30 are slightly removedfrom the inner face of the outer clutch members and at this time theadjustable member 46 at either end of the operating-rod is bearingagainst the key 47, secured to said inner clutch member, and it isevident that any movement of the operating-rod 39 in either directionwill cause either one or the other of the inner clutch members 30 to bemoved into position to cause a frictional contact between the clutchmembers 29 and 30 and cause a continuous revolution of the outer clutchmembers to be transmitted to the inner clutch members to produce arotation of the actuating-shaft 13 in one direction or the other, thedirection of rotation depending upon which pair of clutch members 20 21is in coacting position, it being understood that the outer clutchmembers are continuously driven in opposite directions. This rotationthus accorded to the actuating-shaft 13 will operate the toggle members38 to produce a frictional contact between the shoes 36 and theperipheral flange of the outer clutch members 29 to produce a rotationof the operating rod or member 39, as hereinbefore described. Theoperatingrod lever 44 has secured to its outer end alaterally-projecting rod 48*, on which is mounted a collar 49,interposed between springs 50, the tension of which is adjustable bymeans of nuts 51, threaded to said laterally-projecting rod 48 Thecollar 49 is articulated'to the outer end of the bell-crank lever 52, tothe opposite end of which is pivoted a nut 53, the threads of which areengaged by the threads upon one end of a connector 54, the opposite endof which is threaded to a nut 55, pivoted to the outer end of alever 56,adjustably fulcrumed at 57 to a bracket 58. The lower end of the lever56 is bifurcated, as at 59, the bifurcated end of which engages with thesplit collar 60, 9

mounted ina grooved collar 61, movable endwise upon the driving-shafts27, this endwise movement being caused by a pin 62, extending throughslots in the shaft 27 of said collar 61 and passing througha slidablemember 63, which member is located Within a central bore of saiddriving-shaft 27 and has its outer end provided on two sides with aseries of rack-teeth 64.

The teeth 64 of the slidable member 63 engage with a toothed segment 65,pivoted to the hub of the driving-pulley 28. At right angles to theslidable member 63 and meshing with each segment 65 is a slidable rack66, the outer end of which is articulated to a centrifugal weight 67,pivoted at 68 to a boss upon the inner periphery of the pulley 28. Theouter end of each weight 67 is provided with ears, between which isarticulated a threaded shank passing through a bushing 70, secured toone end of a spring tension device 71, the opposite end of which isprovided with a similar bushing 7 O, in which is threaded acorresponding threaded shank 69, which is articulated to the oppositeWeight 67 at a point 72 intermediate its fulcrum and its free end.

The shanks 69, threaded to the bushings 70 at either end of a spring 71,are threaded in opposite directions, so that by a turn of the tensiondevice 71 this device will act as a turnbuckle and draw the two weightstogether or separate them as desired to vary the tension of the spring71. In the normal position of the centrifugal mechanism, (shown inFig-6) the Weights 67 are somewhat removed from the peripheral flange ofthe pulley 28. and it is obvious thatany increase of speed of the pulleywill cause the weights 6? to be moved outwardly by the centrifugalaction thereon. and this movement will impart, through the racks 66 andsegment 65. a sliding movement to the member cs, which movement willimpart, through the pin c2, passing through the slots in thedriving-shafts 27. a movement of the pivoted lever 5b to cause theoperating member 35) to be moved lengthwise through the medium of theconnector 5-t and levers 52 and H.

A decrease in speed of the pulley 28 will cause the weights to movetoward the axis of the shaft 27 to move the various members mentioned inopposite direction to cause the operating member 3.) to be moved towardthe opposite end of the governor.

To the left end of the operating member 31) is secured a sprocket-wheel73, as shown at the right of Fig. t. This sprocket-wheel being geared tothe member 39 transmits any rotary motion thereof through thesprocketchain Tl to a sprocket-wheel 75, secured to a revoluble member'76, mounted in bearings 77 in the bifurcated standard 78, secured tothe standard 11 at the left end of the machine.

The revoluble member 76 is free to turn within the bearings 77, but isincapable of endwise movement. it is provided with a threaded bore.which engages with the threaded end of the controlling-rod T9, this rodhaving secured thereon a roller 80, which engages with the revolubledisk 81, mounted upon a shaft having secured to its opposite end a gear82, meshing with a gear 83, secured to one of the outer clutch members,said gears 82 83 producing a continuous revolution of the disk 81, thespeed of revolution depending entirely upon the speed of the drivingmember 29. to which the gear 83 is secured or of which it forms a part.

It is obvious from the foregoing description that the rotation of theoperating member 39 may be in either direction, according to which pairof clutch members are operating, and this rotation in either directionof the operating rod or member 3%) is transmitted to the revolublesleeve or member To, thread- 3 ed to the controlling-rod T9, and 1t isobvious that a revolution of said sleeve or member 76 in eitherdirection will act upon said controlling-rod to cause the roller so tobe moved out of its normal postlon. as indicated in Fig. 2,diametrically across the disk 81, the length of movement in eitherdirection depending.

opposite directions and engage with the nuts articulated to the outerends of the levers :3), and so. .It is evident, therefore, that anyincrease or decrease of speed will be transmitted through the pulley 28to the weights pivoted thereto. and the action of these weights will betransmitted through the various mech anisms described to theoperatil'ig-rml 3t). and then through the controlling-rod T.) theconnector 54: will be rotated immediately in the nuts 53 and to increaseor decrease the distance between said nuts, as the case may be. As soon,however, as any changes in the relation of the various parts have beeneffected by the increase or decrease of speed of the motor, so that theroller so has been moved diametrically across the disk 81, therevolution of this disk will act upon the roller 80 to rotate it in onedirection or the otherahmending to which side of the center the rollerhas been moved. The effect of the ,rotation of said roller 80 andconsequent rotation of the controllingrod i.) would be to cause thethreaded end of said controlling-rod to be rotated in the threadedsleeve 76 to thereby cause a return of the roller 80 to its normalposition central to said revoluble disk 81. The return movement of thecontrolling-rod T.) elfects. through the medium of the rack member 8}and gear 85, a rotation of the connector to cause the threaded endsthereof co perating with the nuts 53 and to return the levers .36 and itto their normal positions.

The re volublc sleeve or member To is threaded. as at 86, and hasmounted thereon a nut 87, which has an upwardly-projecting arm 88,provided with rack-teeth engaging with a segment so, secured to apointer 90, pivoted at 91 to a diali 2, said dial being graduated toindicate the position of the gate being controlled by the governor. Thismovement of the nut 81 endwise of the revoluble member T6 is produced bythe revolution of said member To, the threads thereon engaging with thethreaded portion of said nut to cause an endwise movement thereof. thenut 81 being prevented from turning by means of a projection 2);).through which a. rod 9 passes.

The rod 9% is articulated at its opposite end to a lever 95, pivoted atJ6 and connected at 97 to the operating-rod lever it. The rod 9& isprovided with a bearing in the bifurcated arm 77 and has adjustablysecured thereto on i either side of the projection 93 nuts 98, withentirely upon the amount of rotation accorded the operating member 39.The opposite end of the controlling-rod T9 is provided with a rackmember 8st. the teeth of which mesh with a spur-gear 85, secured to andrevolving with the connector 5-.t, and it is obvious that any endwisemovement of the controlling-rod which said projection 93 engages, tocause a movement of said rod in one direction or the other to effect amovement of the operatingrod 39, through the medium of the lever ii, toprevent injury to the various mechanisms, it being required that thenuts 98 should be sufliciently far away from the projection 93 to permitof the ordinary regulation of the speed of the motor without contacttherewith; but

79 will effect a rotary movement of said con- 1 should any unusual speedbe transmitted to nector 5i, the ends of which are threaded in l themechanisms the projection 93 will act upon a nut 98 to effect a movementof the rod 39 to change the relations of the various mechanisms toprevent injury thereto. This movement of the lever 44: is effectedWithout moving the lever 52, the springs 50 yielding to permit this.

As it may be desired at times to operate the regulating mechanism byhand, the shaft 12 may carry fast upon it a bevel-gear 99, meshing witha bevel-pinion 100, upon a spindle 101, turning in a support102 andprovided with a hand-wheel 103. When this hand mechanism is in use, thepin -clutch 17 may be drawn out of the disk 14 to disconnect thegovernor from the motor-controlling shaft.

The operation of the improved governor is as follows; With the parts inthe relation here illustrated power is applied to the pulley 28 to driveit left-handedly at such a rate that normally for the desired speed ofrotation of the machine the weights of the centrifugal mechanism.contained within said pulley will be retained substantially at thecenter of their range of movement, and the various screws, racks, andthe roller 80 will also be at the center of their path. This conditioncontinues until there is a change in the speed of the motor as, forexample, an increase. This results in causing the weights forming partof the centrifugal mechanism to move outwardly under the increasedcentrifugal force generated, and the racks 66, secured thereto, will bemoved thereby, and operating through the segment the slidable member 6 1will be permitted to move in the direction indicated by the arrows inFigs. 3 and 5. This move- .ment of the slidable member will operate uponthe pivoted lever 56 to move the lower end toward the front of themachine, while the upper end is moved in the opposite direction, therebycausing, through the bell-crank lever 52, the pivoted lever 44: to movethe operating rod or member 39 in the direction indicated by the arrowin Fig. 4. This movement of the operating-rod 39 in a direction towardthe left of Fig. 4: causes the clutch members 29 and 30 at the right ofsaid figure to be set so that the actuating-shaft 13 and the operatingmember 39 will be rotated about their axes in unison with the clutchmembers 29 and 30in the direction indicated by the arrow or toward thefront of the machine. This rotation of the actuating member 13 willimpart movement through the gears 15 and 16 to the motor-controllingshaft and cause a closing movement of the gate, if, for example, ahydraulic system is being governed, or a similar operation upon suchmotor as may be connected with the shaft 12 and the speed of which it isdesired to regulate. The rotation of the operating member 39 will causethe revolution of the member 76. As the weights move outwardly to effecta movement of the clutch members through the medium of mechanismsalready described thecontrolling-rod 79 is moved in a direction thatwill operate the connector 54: to increase the distance between the freeends of the levers 52 and 56, so that the lever is will operate morepromptly than it would act otherwise, thus effecting an immediatepartial correction of 'movement is gradually decreased as the rollermoves diametrically across the disk 81 and away from its center. Theaction of the revoluble sleeve on the controlling-rod 79 is constant,while the rotation of the roller 80 is increased with its distance fromthe center of the disk 81. This graduallydecreasing effect of the rack84 upon the gear 85 is due to the increase of speed of the roller 80 asit moves away from the center of the disk 81, which permits the threadedend of the controlling-rod 79 to more rapidly screw into the sleeve 76,and thereby more effectually offset the movement of said rod in theopposite direction effectedby the action of said revoluble sleeve uponsaid threaded end. In other words, during the revolution of the member76 the action of the threads on its bore is to effect a constantmovement of the rod 79 toward the connector 54:, while at the beginningof this movement the rotation of the roller 80 causes only a very slightturning of said threaded end of the rod 79 in the same direction; but asthe roller moves farther from the center of the disk 81 and graduallyincreases in speed the threaded end will turn faster in a direction topractically offset the operation of the revoluble sleeve 76 thereon inthe opposite direction. It is evident, therefore, that the initialaction of the weights willcause the controlling mechanism to eflect aquicker movement of the clutches and regulating mechanism than could besecured if the weights acted alone, and this action on the part of thecontrolling mechanisms gradually decreases, so that there is noopportunity for the various devices to overcorrect. When the speeddecreases and the weights return to their normal operative position, theclutch members are released and the revolution of the operating member39 and member 76 stops. The disk 81 continues to revolve, however, andact upon the roller 80, rotating it and causing the rod 79 to be screwedinto the sleeve 76, and this movement of said 'rod will turn theconnector 54 in its nuts 53 55 to decrease the distance between them andreturn the lever 56 to its normal position, when all of the mechanismsforming a part of the governor will be ready to earc for any furtherincrease or de crease in the speed of the motor.

it is obvious that in the operation of the various controllingmechanisms as described the roller 80 will remain at rest at the centerof the disk 81, while the centrifugal weights occupy their normalposition; but as soon as the controlling-rod carries the roller otl' thecenter to a point having rotary travel the roller and rod upon which itis mounted will be operated thereby in the sleeve T6 until it againreaches the axis of the revoluble disk 81.

it will be evident that the farther the weights 1 depart from the normalthe farther the roller 80 will be carried from the center of the diskand the more rapidly the shaft upon which said roller is mounted will berotated, and therefore the neutralizing of the return of the weightswill be at a rate varying with the extent of their movement and thedistance which the rod has been moved, being at lirst most rapid, thengraduallydecreasing as the roller returns to the center. Theneutralizing effect, will, moreover, be substantially proportional tothe rate of return of the weights to the normal.

The action of this improved governor will be to secure a more rapid orgreater correction for changes of speed of the motor governed arisingfrom change of load or the like without permitting this correction tooverrun and producing a seesawing of the speed in opposite directions,and in the present mechanism this is accomplished without any hydraulicmechanism or valves. All the various controlling and regulatingmechanisms being mechanically connected and free from the fluctuation ofthe hydraulic pressure or other power, they are less liable at times tobecome 1 inoperative and inetl'eetive.

By the employment of mechanical connections throughout the operation ofthe governor it is absolutely positive in its operation. This governormechanism, moreover, secures an almost absolutely constant rotation ofthe motor system driven thereby, while applying at all times ample powerto overcome any re- 3 sistance to movement of the gate or other mg lulating system.

it is believed that with the foregoing description the operation of thisgovernor will be fully understood without further description.
